Parking near Dalmarnock station looks possible (about 15 minutes walk to the ground) or park at Rutherglen and get the train to Glasgow Central for the tickets and back out to Dalmarnock for the game.
Some of the industrial estates allow match parking but you've still got to factor getting in and out for tickets. Another site says lots of street parking with the obligatory urchins asking to "mind yer car mister".
Dalmarnock station is a good idea, do a left and there is a big Tescos just down the road from there and you can park on the street between the two. Easy to get away back onto the motorway after the game too. It is a bit dodgy, but no more than any other place near a big city ground. No kids minding your car and no permits as far as I remember. Main road too, so no back streets to worry about.
